Question

How many atoms in 4.75 moles of gold, au?

Answer 1

In 4.75 moles of gold, there are approximately 28.595×1023 gold atoms, calculated by multiplying the number of moles by Avogadro's number (6.02×1023 atoms per mole).

Step-by-step explanation:

To find out how many atoms are in 4.75 moles of gold (Au), we will use Avogadro's number, which is 6.02×1023 atoms per mole. This is a fundamental concept in chemistry that relates the number of particles in a substance to the amount of substance in moles.

To calculate the total number of atoms, the equation is as follows:

Number of atoms = Number of moles × Avogadro's number

For 4.75 moles of gold, the calculation would be:

Number of atoms = 4.75 moles × 6.02×1023 atoms/mole

Number of atoms = 28.595×1023 atoms

Therefore, there are approximately 28.595×1023 gold atoms in 4.75 moles of gold.

Answer 2

The number of atoms in 4.75 moles of gold (Au) is found using Avogadro's number, which is 6.022Ă—1023 mol-1. Determine the number of atoms by multiplying 4.75 moles by Avogadro's number. The number of atoms in 4.75 moles of gold is 2.8605172125000205e24.
